New surveillance video has surfaced that possibly shows the last appearance of Kamille “Cupcake” McKinney before her abduction Oct. 12.

“From what we’ve been able to determine so far, this is the last known location that we could determine where she was,” Smith said.

Birmingham Police Chief Patrick Smith said the surveillance video was taken from the Tom Brown Village area shortly before law enforcement was alerted to her disappearance.

The video shows two small children playing in a courtyard and two adults walking by. According to police, Cupcake is believed to be in the video. One of the men walking by is deemed a suspect and the other a person of interest.

“We’re hoping that someone will see this video and recognize the individual on there or he himself will say ‘Hey, that’s me,’ and whatever information they can provide will be greatly appreciated,” Smith said.

Currently, there are two people of interest in Cupcake’s kidnapping: Patrick Devone Stallworth, 39, and Derick Irisha Brown, 29. Both were arrested earlier in the week on unrelated charges. Brown remains in jail without bond while Stallworth posted bond and has been free since Thursday. Smith maintained his belief that there are others who may have been involved in the case.

“Everyone is a person of interest at this point in the investigation,” Smith said.

The second child in the video has been identified. However, police have decided not to release the identity of the child or their family.

Smith said there has yet to be a motive established in Cupcake’s kidnapping. However, he said he believes the abduction was not thought out well in advance and that it may have been carried out as early as 20 minutes before she disappeared.

“I don’t believe that a lot of planning went into it,” Smith said. “I think that maybe it was something done impromptu.”

Smith said police are including K-9 units in the search for Cupcake.

According to Smith, there will be a grid search Sunday in the community. The area for this search is believed to be a place frequented by the person of interest.

Anthony hosted a press conference on Friday morning to provide more information about representing Stallworth.

He was held on a $500,000 bond. According to the Jefferson County Jail in Bessemer, he posted bond and was released at 3:22 a.m. Thursday.
